and all that is needed is a tiny sample of their DNA. When an organism, say a fish, moves through the environment it’s constantly shedding bits of itself. A creature can shed anything from dead skin ...

Researchers created DNA tools that detect deep-sea marine animals like squids and octopuses by analyzing ocean water.

Environmental DNA and climate change data suggest that vegetation scarcity led to the mass extinction of herbivore species, including Arctic mammoths. Studies The Scientist covered this year ...

The researchers on Viking's Octantis cruise ship are studying environmental DNA (eDNA) — bits of genetic material that float ...

The results, published March 31 in PeerJ, represent a new direction for environmental DNA (eDNA) research that could one day lead to advances in forensic science and public health, in addition to ...

Internal and external environmental factors, like gender and temperature, influence gene expression. Sex-limited traits are also autosomal. Unlike sex-influenced traits, whose expression differs ...

DNA integrity is always under attack from environmental agents like skin cancer-causing UV rays. How do DNA repair mechanisms detect and repair damaged DNA, and what happens when they fail?
